WikiLeaks is a site that publishes so-called classified information that has been leaked to it. By its very nature, we cannot establish the accuracy of such a site, because we (as mere mortals in this political game) do not have access to the original classified information, or the supporting documentation behind it. In point of fact, leaking of classified information has been going on for years, sometimes for good, sometimes for bad - and, interestingly, not all leaked information is accurate - it is sometimes deliberate misdirection - and we are left with no viable way to authenticate it either way.
In the final analysis, leaking of classified information is treason, and is potentially punishable by execution.

What is the best definition for random sampling?
There are two equivalent definition.
Definition 1: A simple random sample is one for which each element has the same probability of being included in the sample.
Definition 2: A simple random sample is one where all sample of that size have the same probability of being selected.
Although the words are similar, the first refers to the selection of individuals from the population whereas the second refers to the samples.
No individual can be said to have discovered the rules of probability. Some people that made important contributions are Gerolamo Cadarno, Pierre de Fermat, Blaise Pascal and Chritiaan Huygens.
Pierre-Simon Laplace wrote what many consider to be the definitive work.
